An unknown body revolves around Earth, astronomers baffled recently.
The investigators consider that the extraterrestrial body, 373 miles (600 km) on the Earth, could be a trunk, which some consider like rest of a rocket launch, but the experts did not identify their source due to their small size.
Experts believe that this strange satellite can be a piece of weak material, such as rockets, according to the British newspaper "Daily Express."
This intriguing object, called A10bMLz, was detected on Friday for the first time by an ATLAS telescope.
The object was also analyzed by astronomers at the London Northolt Branch Observatory and was described as "extremely light" and stretches for several meters.
"This refers to what is known as the empty garbage bag, a piece of lightweight material (possibly fine metal), followed by the launch of a rocket," said the Northolt Observatory.
"Orbit the Earth in an unusual orbiting back, at an average distance of 262,000 km."
